Vol 2 Chapter 354: Pneumonia and penicillin (Popular Science

Laboratory, main laboratory.
In the room, Pandora washed a lot of test tubes, put them on the test tube rack, his eyes were shining with pride. Extend a finger and point at the test tube.
"Ita!" One!
"Toke!" Two!
"Sara!" Three!
"Spa!" Four!
"Wa..." When Pandora just counted to the fifth, his eyes blinked, and he felt that the test tube wall was dirty and not cleaned. He reached out and carefully removed it from the test tube rack. Brush it again.
At this moment, with a bang, the laboratory door was knocked open, and Li Cha stumbled and walked in pale.
"Wow!"
The glass tube in his hand was crushed directly, Pandora turned around and looked at Richard with surprise.
At this time, Richard was wearing a thick mask, covering her mouth and nose tightly, and didn't talk much at all, but simply said to Pandora: "Pandora, you go to the courtyard and wait for me. I tell you to come in and come in again."
"scare?"
"Hurry up." Li Cha breathed heavily and quickly under his hand and finally took a deep breath. "Obey—"
Pandora's eyebrows fell, her eyes flickered, and finally he listened to Richard's words, and walked out to the courtyard.
Richard immediately closed the laboratory door, closed and sealed all doors, windows, entrances and exits, and closed the entire laboratory.
After doing all this, he took off his mask and began to breathe heavily.
This is also a matter of no help, he could not help but carelessly. Generally speaking, the infectivity of pneumonia is very weak, but in the current world, some people start to use this as a weapon. Who knows if there are some mutations? He didn't want Pandora to give it a try.
Admittedly, Pandora relies on the dragon's strong physique, even if infected, there is a great chance of immunity, but whether or not to take the risk or not.
Thinking this way, Li Cha calmed down and fully sensed the condition of the body. Now the typical symptoms of pneumonia, such as cough, fever, difficulty breathing, and chest pain, are all present and are getting worse. The most serious is fatigue, which is a common manifestation of patients with pneumonia. There is a probability of more than 9o%, and even if it is cured, it will last for a long time.
At this point, Richard felt that his body was sinking like lead, and it was difficult to move his fingers. He wanted to fall to the ground and sleep.
But he was very clear in his heart that it must never be so. If he sleeps now, he may never wake up. You must find a way to solve pneumonia.
To solve pneumonia, we must figure out what is going on.
His pneumonia is caused by the bacteria spores of mushrooms. According to research on modern earth, although it is relatively rare, it is not without relevant cases.
In fact, the most similar to his current situation is the mushroom lung.
Mushroom lung is a kind of lung disease on the modern earth. During the mushroom harvest period, the pickers are extremely prone to lung diseases. The mechanism is that a large number of fungal spores cause invasion of the respiratory system, causing a series of lesions. The incubation period of this disease varies, if it is long, it can be extended to three months, if it is short, it can be done in 3o minutes.
Once done, symptoms such as severe cough, sputum, chest pain, chest tightness, and breathlessness, accompanied by headache, dizziness, palpitation, muscle aches, heat, nausea, vomiting, loss of appetite and other systemic symptoms and gastrointestinal symptoms.
The difference between him and the mushroom lung is that the mushroom lung is an allergic reaction and will return to normal after disengagement; he is heavier pneumonia, and it will only get worse without effective targeted treatment.
How to treat it?
Richard glanced at the many wooden frames in the laboratory, looking at the many materials on the wooden frames, his eyes flashing.
For diseases caused by bacteria, the most effective treatment is, of course, the use of antibacterial drugs, which is basically the common sense of all modern people.
On the modern earth, because antibacterial drugs are so widely used, even the phenomenon of abuse has occurred, resulting in the generation of highly resistant bacteria.
In the current wizard-like world of the Middle Ages, there is no such concern-all germs have not been tested by antibacterial drugs. Compared with the companions of germs on modern earth, they are regarded as the small white of the small white.
If we say that the germs invade the human body, it is equivalent to violently breaking into a robber who does not defend the village. The antibacterial drug against the germs is the tried and tested lion of war in the past. On the way back, I was bored and idle, and I killed a group of robbers who looked like thieves-never used antibacterial In the world of medicine, the effect of the second use of antibacterial drugs is simply a 12o% bonus.
The question now is, where can I get antimicrobials?
The preparation of antibacterial drugs is simple and simple, and difficult.
To be simple, as common sense, everyone on modern earth understands that the most commonly used antibiotic is penicillin.
The difficulty is, how did you get penicillin initially?
If you start from the beginning, then you have to push the time...to the summer of July 1928 on modern earth. The careless British scientist Fleming cultivated a large number of Staphylococcus aureus in the laboratory in order to write a paper on Staphylococcus.
During the cultivation process, Fleming forgot to cultivate, and even without the lid of the petri dish, he went to the countryside for a holiday. It wasn't until September when I returned from my vacation that I remembered the cultivation. Looking back at the laboratory, a mold had grown in the corner of the petri dish, and Staphylococcus aureus near the mold died dead.
Fleming may be careless, but his sensitivity is not bad. Immediately conducted many experiments and studies, and finally determined that the mold grown in the petri dish can secrete special substances that can kill a variety of pathogenic bacteria. He was very excited to name this mold "Penicillium" and the secreted substance "Penicillin" while writing a thesis table.
By the time the paper appeared in the UK, it was already February 13, 1929.
Is this the end of the story?
Obviously not, for the penicillin exhibition, it is just the beginning.
Admittedly, Fleming was very lucky to have penicillium that has been in nature for a long time, but how to purify it is a problem and cannot be used for clinical treatment.
It wasn't until 1938 that the team led by Chane, Flory and Heatley of Oxford University in the United Kingdom successfully extracted penicillin-this was already 1o years after penicillin was present, and 9 years after the thesis table.
Extracted, the story is still not over, because the initial penicillium produced too little penicillin.
The Fleming Laboratory used the propagation of the penicillin vaccine to achieve a penicillin output of only 4 units per milliliter or even lower. It can only be used for one month after a continuous production of ~EbookFREE.me~ After many efforts, The research team in the United States designed the corn syrup culture fluid to increase the production of penicillin by ten times-4o units per milliliter, which is still not available to ordinary people.
Later, researcher Mary Hunt, in the Peoria market in Illinois, USA, now has a moldy cantaloupe epidermis covered with Penicillium. She used this cantaloupe for multiple screening and cultivation, and finally the output of penicillin reached 25o units per milliliter. Researchers at the University of Wisconsin have used ultraviolet light to irradiate the strain to mutate it and increase the output to 2,5oo units per milliliter.
25oo units per ml! This is already the limit of an era.
And how many units of penicillin do a person need for normal treatment?
According to the modern treatment methods of the earth, even ordinary infections require the injection of 960,000 units of penicillin per day.
960 thousand!
9, 6oo, ooo, compared to 2, 5oo!
384o times!
It is completely conceivable how big the gap is.
In fact, it wasn't until the Penicillium had been present for a long time that the countless strains of bacteria had improved the production of penicillin to 5oooo units per milliliter, before it was commercially produced and used on a large scale. Before commercial production and large-scale use, penicillin is more expensive than gold, which is really not a joke.
This is the problem!
Li Cha narrowed his eyes.
If he wants to be treated with penicillin, even if he is very lucky, he can get the penicillium vaccine in nature in an instant, and it will take at least one month before he can try to treat himself. Actually, a sufficient amount of penicillin will not be available after one year.
By that time, the body should be cool.
Well, it's cool.
